Soil pH – The Foundation for Nutrient Availability

Soil pH Blog Image DRAFT1

Every nutrient's availability is affected by soil pH.

Soil pH is the foundation and main governing parameter of soil fertility. Every nutrient’s availability to plants is affected by soil pH – some more so than others – which is why correcting and maintaining soil pH at adequate levels is so important.

Phosphorous (P) availability is the most affected nutrient by pH because the chemistry of P is such that it loves to react with other minerals in the soil at varying pH levels. At high pH, P is very attracted to calcium, while at low pH, P is very attracted to aluminum and iron. When P reacts with calcium, aluminum, or iron, it forms insoluble compounds that plants cannot easily access.

Nitrogen (N) and Potassium (K) are also affected by pH, but not in the same way as P. At low pH, aluminum and iron increase in availability and “out-compete” nutrients like N and K in the soil, leaving N and K susceptible to leaching from the soil profile.

Maintaining proper pH protects fertilizer investments.

With the substantial investment made on N, P, and K fertility programs, it is easy to see why maintaining appropriate pH is paramount to protecting fertilizer investments. Further, crops need sufficient access to these nutrients in order to obtain maximum yield and further return the investment growers make on these important nutrients.

Our philosophy is that soil pH should be corrected and then maintained with yearly or every-other-year, lower rate applications to avoid the pH rollercoaster that can occur with 4- or 5-year aglime application regimens. Our product, 98G, is a pelletized lime that corrects and maintains soil pH. It’s easy to apply and works well in variable rate application programs.

By measuring and managing soil pH, you are ensuring that growers are set up for a high-yielding crop and fertilizer investments are being put to work.
